# Capture a continuous CMIF movie using the Indigo video library and board
|

|

|

# Usage:
|
||||
#
|
||||
# makemovie [-r rate] [-w width] [moviefile]
|
||||
|
||||
|
||||
# Options:
|
||||
#
|
||||
# -r rate : capture 1 out of every 'rate' frames (default 1)
|
||||
# -w width : initial window width (default interactive placement)
|
||||
# -d : drop fields if needed
|
||||
# -g bits : greyscale (2, 4 or 8 bits)
|
||||
# -G : 2-bit greyscale dithered
|
||||
# -m : monochrome dithered
|
||||
# -M value : monochrome tresholded with value
|
||||
# -f : Capture fields (in stead of frames)
|
||||
# -n number : Capture 'number' fields (default 60)
|
||||
#
|
||||
# moviefile : here goes the movie data (default film.video);
|
||||
# the format is documented in cmif-film.ms
|
||||
|
||||
|
||||
# User interface:
|
||||
#
|
||||
# Start the application. Resize the window to the desired movie size.
|
||||
# Press the left mouse button to start recording, release it to end
|
||||
# recording. You can record as many times as you wish, but each time
|
||||
# you overwrite the output file(s), so only the last recording is
|
||||
# kept.
|
||||
#
|
||||
# Press ESC or select the window manager Quit or Close window option
|
||||
# to quit. If you quit before recording anything, the output file(s)
|
